In this paper, we assess the potential of Support Vector Machine (SVM) approach for forecasting the demand of Canadian Armed Forces (CAF) spare parts and we introduce a forecasting evaluation method using inventory cost performance curves based on over and under forecast error. We compare, using a well-known use case presented in the literature, the results given by SVM algorithm to those given by several popular forecasting approaches. We find that SVM performs better than, or equivalently to, the other methods for this use-case. We also perform some forecasting experiments using the historical data of forty CAF spare demand series with 84 periods (months) each. The results of the experiments show that SVM may offer forecasting improvements over many other methods however the performance of SVM is not quite as good on intermittent data (time series with a high Average Demand Interval-ADI and low Coefficient of Variation-CV).","PeriodicalId":153800,"journal":{"name":"2018 6th International Symposium on Computational and Business Intelligence (ISCBI)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122200479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
